The RU-AFC2 is a stereo bi-directional audio format converter. The bi-directional format allows the RU-AFC2 to fully convert the stereo input and stereo output of a consumer audio product to professional balanced standards. It can equally convert the stereo input and stereo output of a professional audio product to consumer unbalanced standards. The audio fidelity, low noise, low distortion and excellent crosstalk performance of the RU-AFC2 are ideally suited to the most critical applications. The RU-AFC2 has been carefully engineered in meticulous detail to provide the ultimate audio interface package available. Unbalanced audio connections are available on front-panel RCA jacks. Balanced audio connections are available on front-panel XLR jacks and on rear-panel detachable terminal blocks.The shield connections of the XLR output jacks are connected to the case through a rear-panel ground-lift switch. The unbalanced to balanced section includes an additional MONO summed output on a rear-panel detachable terminal block which may be wired balanced or unbalanced. The mono output may be used to drive patch-bay jacks, powered monitors or subwoofer amplifiers. Each of the left and right outputs is equipped with a dual-LED VU-meter. The intensity of the green LED is proportional to the audio level. The red LED flashes at the calibrated output level, -10 dBV unbalanced or +4 dBu balanced. An individual multi turn level trimmer is provided on the front panel for each output channel. The RU-AFC2 operates from ground-referenced 24 Vdc. Use the RU-AFC2 individually, or combine it with other RDL products as part of a complete audio/video system.Main Features:Unparalleled Audio PerformanceUnbalanced to Balanced Audio ConversionAdditional Summed MONO OutSwitch-Selectable Ground Lift for XLR Output JacksBalanced to Unbalanced Audio ConversionUnbalanced RCA Connections on Front PanelBalanced XLR Connections on Front PanelBalanced Connections on Rear Panel Detachable Terminal BlocksFront-Panel Multi-Turn LEVEL TrimmersDual-LED VU Meter for Each ChanneGold-Plated ConnectorsExceptional Headroom and Frequency Response1/3 Rack, High Density Rack MountingSpecifications:Unbal to Bal Section:(Referred to 10 dBV input feeding +4 dBu)Inputs (2):Unbalanced linelevel, +25 dBV max.Input Connectors (2):RCA Phono jack (left and right)Outputs (3):+4 dBu balanced (left, right, mono sum), +25 dBu max.Output Connectors (4):XLR (2) and/or detachable terminal block (left and right); detachable terminal block (mono sum)Gain adjustment:-25 dB to +9 dB (rel. +4 dBu)Frequency Response:10 Hz to 150 kHz (+/ 0.25 dB)THD+N:< 0.005%Noise:< 90 dB (below +4 dBu)Crosstalk:< 80 dB (20 Hz to 20 kHz)Headroom:> 20 dBBal to Unbal Section:(Referred to +4 dBu input feeding 10 dBV)Inputs (2):Balanced linelevel, +25 dBu max.Input Connectors (3):XLR (2) or detachable terminal block (left and right)Outputs (2):-10 dBV unbalanced (left and right), +17 dBV max.Output Connectors (2):RCA Phono jack (left and right)Level adjustment:28 dB to +5 dB (rel. -10 dBV)CMRR:> 80 dB (50 to 120 Hz)Frequency Response:10 Hz to 150 kHz (+/ 0.25 dB)THD+N:< 0.001%Noise:< 100 dB (below 10 dBV)Crosstalk:< 90 dB (10 Hz to 20 kHz)Headroom:> 20 dBAmbient Operating Environment:0 C to 55 CPower Requirement:GROUNDREFERENCED, 24 Vdc @ 60 mA (idle), 100 mA (max)Package Type:Cardboard BoxPackage Dimensions:6 x 6 x 2.625 in.Shipping Weight:1.53 lbs.WEEE weight:1.285 lbs.Tariff code:8543.70.9860
